That's a whopping 21 different artists! As expected, most of the repeat performers are G.O.O.D. Music signees—although where's Mr. Hudson?—but there's also quite the murderer's row of guests: Jay-Z, R. Kelly, Raekwon and others. Also notice that, even though Cruel Summer is Kanye's baby, he only appears on just over half the tracks.

What's the magic number of rappers per track? At least according to G.O.O.D. Music, it's either two or three. (This is a subject that requires a lot of further study, though.) And even more interesting is the fact that only one guy got a track all to himself: Kid Cudi.
